Parasites

The Acanthocephala (gr. Acanthus - thorn Kephale - head) is a phylum of parasitic worms, characterised by the presence of an evertable proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host. Acanthocephalans typically have complex life cycles, involving a number of hosts, including invertebrates, fishes, amphibians, birds, and mammals. About 850 species have been described. ...more on Wikipedia about "Acanthocephala"

Acanthocheilonema viteae is an important parasite. It is a nematode. ...more on Wikipedia about "Acanthocheilonema viteae"

The Amblycera are a large suborder of lice, parasitic on both birds and mammals. The Amblycera are considered the most primitive suborder of lice. They roam freely over the surface of their host and, unlike other lice, do not form permanent attachments. They feed by chewing soft areas of skin, causing an area of localised bleeding from which they drink. ...more on Wikipedia about "Amblycera"

Ancylostoma is a genus that includes some species of hookworm. ...more on Wikipedia about "Ancylostoma"

Anisakis is a genus of parasitic nematodes, which have a life cycle involving fish and marine mammals. They are infective to humans and cause Anisakiasis, and fish which have been infected with Anisakis spp. can produce an anaphylactic reaction in people who have become sensitized to Immunoglobulin E. ...more on Wikipedia about "Anisakis"

The Apicomplexa are a large group of protozoa, characterized by the presence of an apical complex at some point in their life-cycle. They are exclusively parasitic, and completely lack flagella or pseudopods except for certain gamete stages. Diseases caused by Apicomplexa include: ...more on Wikipedia about "Apicomplexa"

Ascaridia galli is a nematode parasite that causes ascariasis, or worm infection, in poultry. ...more on Wikipedia about "Ascaridia galli"

The Ascetosporea are a group of protists that are parasites of animals, especially marine invertebrates. There are two groups, the haplosporids and paramyxids, which are not particularly similar morphologically but consistently group together on molecular trees, which place them near the base of the Cercozoa. Both produce spores without the complex structures found in similar groups (such as polar filaments or tubules). ...more on Wikipedia about "Ascetosporea"

The Aspidogastrea (gr. aspid - shield, gaster - stomach/pouch) is a small group of flukes comprising about 80 species. It is a subclass of the trematoda, and sister group to the Digenea. Species range in length from approximately one mm to several cm. They are parasites of freshwater and marine molluscs and vertebrates ( cartilaginous and bony fishes and turtles). Maturation may occur in the mollusc or vertebrate host. None of the species has any economic importance, but the group is of very great interest to biologists because it has several characters which appear to be archaic. ...more on Wikipedia about "Aspidogastrea"

The Australian Christmas Tree (Nuytsia floribunda) is a parasitic tree found in Western Australia, particularly around Christmas time ( summer). It is known for its bright yellow foliage and can grow to 10 m tall. It is a member of the mistletoe family. ...more on Wikipedia about "Australian Christmas tree"

Balantidium coli is a species of ciliate protozoan, and is the only one that is a pathogen of humans. It is carried by pigs, rats, primates (including humans), rats, horses, cattle and guinea pigs. It is transmitted within or between these species mostly via fecal transmission. Pigs are the most significant reservoir hosts, though they show few if any symptoms. ...more on Wikipedia about "Balantidium coli"

Baylisascaris is a genus of roundworms that infest more than fifty animal species. ...more on Wikipedia about "Baylisascaris"

Oestridae (also called botfly or bot fly) is a family of Oestroidea. It is one of several families of hairy flies whose larvae live as parasites within the bodies of mammals, such as the Desert Woodrat. ...more on Wikipedia about "Botfly"

Brachylaima is a newly discovered human trematode helminth infection that causes diarrhoea. ...more on Wikipedia about "Brachylaima"

Brugia pahangi is an important parasite. It is a microfilarial nematode known to infect the lymph vessels of domestic cats and wild animals. ...more on Wikipedia about "Brugia pahangi"

The candirú or canero (Vandellia cirrhosa) is a freshwater fish in the group commonly called the catfishes. It is found in the Amazon River and has a reputation among the natives as the most feared fish in its waters, even over the piranha. The species grows only to a size of an inch in length and is eel shaped and translucent, making it almost impossible to see in the water. The candiru is a parasite. It swims into the gill cavities of other fishes, erects a spine to hold itself in place, and feeds on the blood in the gills, earning it a nickname as the "vampire fish of Brazil". ...more on Wikipedia about "Candirú"

The Caryophyllideans are a group of tapeworms that infect fish and annelids (segmented worms) with a simple scolex or "head." Worms in this order only have one proglottid, which is believed to be the primitive condition for tapeworms. ...more on Wikipedia about "Caryophyllidea"

In biology, Cestoda is the class of parasitic flatworms, called tapeworms, that live in the digestive tracts of vertebrates as adults and often in the bodies of various animals as juveniles. In a tapeworm infection, adults absorb food predigested by the host, so the worms have no need for a digestive tract or a mouth. Large tapeworms are made almost entirely of reproductive structures with a small "head" for attachment. Symptoms vary widely, depending on the species causing the infection. Symptoms may include upper abdominal discomfort, diarrhea, and loss of appetite. However, infestations are usually asymptomatic. Worm segments or eggs may be found in the stool of an infected person. ...more on Wikipedia about "Cestoda"

Cestodaria is one of two subclasses of the class Cestoda which claims the common tapeworm as one of its more predominant members. The Cestodaria subclass is made up of Amphilinidea and Gyrocotylidea. ...more on Wikipedia about "Cestodaria"

The Clonorchis sinensis is a human liver fluke in the class Trematoda, Phylum Platyhelminthes. This parasite lives in the liver of humans, and is found mainly in the common bile duct and gall bladder, feeding on bile. These animals, which are believed to be the third most prevalent worm parasite in the world, are endemic to Japan, China, Taiwan, and Southeast Asia, currently infecting an estimated 30,000,000 humans. ...more on Wikipedia about "Clonorchis sinensis"

Crab lice (singular, louse), scientific name Phthirus pubis and commonly called "crabs" due to their resemblance to the crab, are one of three kinds of human lice in the large group of lice families, the others being head lice and body lice, which live in clothing. They are wingless, about 1 to 3 mm long. They attach themselves to hair strands, and hatch out of pods with lids, or "nits", that are too tightly attached to be brushed off but must be removed by pulling with the nails or a fine-toothed comb. ...more on Wikipedia about "Crab louse"

Tapeworms of the order Cyclophyllidea (the cyclophyllid cestodes) are the most important cestode parasites of humans and domesticated animals. All have multiple proglottid "segments," and all have four suckers on their scolex ("head"), though some may have other structures as well. Proglottids of this order have genital openings on one side (except in the family Dilepididae, which has genital openings on both sides), and a compact yolk gland or vitellarium posterior to the ovary. ...more on Wikipedia about "Cyclophyllidea"

Cylicocyclus nassatus is a very common species of cyathostomin, which are important intestinal parasites of horses. Cyathostomins, including C. nassatus, are nematodes. ...more on Wikipedia about "Cylicocyclus nassatus"

Digenea (Gr. Dis - double, Genos - race) is a subclass within the Platyhelminthes consisting of parasitic flatworms with a syncytial tegument and, usually, two suckers, one ventral and one oral. They are particularly common in the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6000 species have been described to date. ...more on Wikipedia about "Digenea"
